Creating and managing HL7v2 messages

This page explains how to ingest, create, label, view, and delete HL7v2 messages.

Overview of creating and ingesting HL7v2 messages

A created message originates from Google Cloud and is sent to a care system (such as a hospital). To create a message, use the messages.create method. In contrast, an ingested message comes from a care system and is ingested into Google Cloud. To ingest a message, use the messages.ingest method.

When the Cloud Healthcare API ingests a message from a care system, the Cloud Healthcare API sends an acknowledgment message (ACK) to the remote care system and generates a response. This response contains an hl7Ack field and value, which verifies that the message was accepted. Note the following important information about the hl7ack field's value:

The value contains a response type. An AA response type indicates Application Accept, meaning that the message was validated and successfully ingested.
The sending facility and the receiving facility are reversed.
The value contains the original message's control ID.

After a message is created and sent to a care system, the Cloud Healthcare API expects the care system to return an ACK. Note that ACK messages are not persisted in HL7v2 stores.

Message ingestion and creation with an MLLP adapter

See MLLP and the Google Cloud Platform MLLP adapter for information on the minimal lower layer protocol (MLLP), which is the protocol over which HL7v2 messages are delivered. If you are ingesting and creating HL7v2 messages, you will need to use an MLLP adapter to communicate with the Cloud Healthcare API.

A tutorial is provided that gives instructions on how to configure an MLLP adapter to communicate securely with the Cloud Healthcare API.

Ingesting and creating an HL7v2 message

The following samples show how to ingest an HL7v2 message and how to create one. If you need an example HL7v2 message to use with the samples, you can download the hl7v2-sample.json JSON file.

For more information, see projects.locations.datasets.hl7V2Stores.messages.ingest for ingestion and projects.locations.datasets.hl7V2Stores.messages.create for creation.

curl command

To ingest an HL7v2 message, make a POST request and provide the name of the parent dataset, the name of the HL7v2 store, a message, and an access token. The following sample shows a POST request using curl and an example JSON file called hl7v2-sample.json.

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data-binary @hl7v2-sample.json \
     "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages:ingest"

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

200 OK

        "type": "HNMBR"
      }
    ]
  }
}

PowerShell

To ingest an HL7v2 message, make a POST request and provide the name of the parent dataset, the name of the HL7v2 store, a message, and an access token. The following sample shows a POST request using Windows PowerShell and an example JSON file called hl7v2-sample.json.

$cred = gcloud auth print-access-token
$headers = @{ Authorization = "Bearer $cred" }

Invoke-WebRequest `
  -Method Post `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile hl7v2-sample.json `
  -Uri "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages:ingest" | Select-Object -Expand Content

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

200 OK

        return ""

Setting the segment terminator

The HL7v2 message format requires that segments be terminated using the return character, \r, but you can configure the HL7v2 store to accept HL7v2 messages with a non-standard terminator, such as \r\n.

Consider the following HL7v2 message, which uses the default \r as the segment terminator. This message will be accepted by default when you create an HL7v2 store.

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\rEVN|A01|20110613083617|\rPID|1||21004053^^^^MRN||SULLY^BRIAN||19611209|M|||123 MAIN ST^^MOUNTAIN SPRINGS^CO^80439|\rPV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\r

The following message is identical to the message shown above, except that it uses \r\n as the segment terminator:

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\r\nEVN|A01|20110613083617|\r\nPID|1||21004053^^^^MRN||SULLY^BRIAN||19611209|M|||123 MAIN ST^^MOUNTAIN SPRINGS^CO^80439|\r\nPV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\r\n

To store the message, configure the ParserConfig object in the HL7v2 store and set the segmentTerminator field to a base64-encoded version of \r\n. The following samples show how to configure segmentTerminator in ParserConfig when you create an HL7v2 store. If you have an existing HL7v2 store, you can edit it and provide the ParserConfig body. After setting the segment terminator, you can create or ingest the message as shown above.

curl command

To create an HL7v2 store and set the segment terminator to \r\n, make a POST request and provide the name of the parent dataset, the name of the HL7v2 store, a parserConfig object with the segmentTerminator set to DQo= (the base64-encoded version of \r\n), and an access token. The following sample shows a POST request using curl.

curl -X POST \
    --data "{
      'parserConfig': {
        'segmentTerminator': 'DQo='
      }
    }" \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

200 OK

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID",
  "parserConfig": {

  }
}

  }
}

Using a null segment header

Typically, an HL7v2 message will contain a message header segment (MSH) that defines the message's source, intent, purpose, destination, and other specifics of the message. The MSH is particularly useful for searching and filtering messages. However, you can store messages that do not contain an MSH by configuring the ParserConfig object in the HL7v2 store and setting the allowNullHeader field to true.

The folllowing sample message contains a Patient Identification (PID) segment, but no MSH:

PID|1||21004053^^^^MRN||SULLY^BRIAN||19611209|M|||123 MAIN ST^^MOUNTAIN SPRINGS^CO^80439

The following samples show how to configure allowNullHeader in ParserConfig when you create an HL7v2 store. If you have an existing HL7v2 store, you can edit it and provide the ParserConfig body. After setting allowNullHeader to true, you can create or ingest the message as shown above.

curl command

To create an HL7v2 store and store messages that don't contain an MSH, make a POST request and provide the name of the parent dataset, the name of the HL7v2 store, a parserConfig object with allowNullHeader set to true, and an access token. The following sample shows a POST request using curl.

curl -X POST \
    --data "{
      'parserConfig': {
        'allowNullHeader': true
      }
    }" \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \

    "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

  }
}

Labeling an HL7v2 message

You can add one or more key-value labels to a message. One use case for this could be adding status labels to a message so that an application can query for messages with a specific status. For example, if you are doing batch processing (ETL), and you label some messages with Status: Processed and leave other messages without any label, you could then query for only the processed messages.

The following samples show how to add labels to an HL7v2 message. For more information, see projects.locations.datasets.hl7V2Stores.messages.patch.

curl command

To add labels to an HL7v2 message, make a PATCH request and provide the name of the parent dataset, the name of the HL7v2 store, the message ID, the label data to update, an update mask, and an access token. The following sample shows a PATCH request using curl.

curl -X PATCH \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    --data "{
      'labels': {
        'KEY' : 'VALUE'
      }
    }" "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID?updateMask=labels"

Getting HL7v2 message contents

The following samples show how to get the contents of an HL7v2 message. To determine what parts of the message to return, supply the view query parameter with one of the following options:

MESSAGE_VIEW_UNSPECIFIED: Not specified, equivalent to FULL.
RAW_ONLY: Server responses include all the message fields except parsedData field.
PARSED_ONLY: Server responses include all the message fields except data field.
FULL: (Default) Server responses include all the message fields.

The following samples show how to get the contents of an HL7v2 message using the FULL, RAW_ONLY, and PARSED_ONLY views.

For more information, see projects.locations.datasets.hl7V2Stores.messages.get.

Using the `FULL` view

You do not need to explicitly set the FULL view, as FULL is the default value. However, in the following curl and Windows PowerShell samples, the FULL view is added as a query parameter for completeness.

curl command

To get the contents of an HL7v2 message using the FULL view, make a GET request and provide the name of the parent dataset, the name of the HL7v2 store, the message ID, the view, and an access token. The following sample shows a GET request using curl.

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID?view=FULL"

If the request is successful, the server returns a 200 OK HTTP status code and the response in JSON format:

Deleting an HL7v2 message

The following samples show how to delete an HL7v2 message. For more information, see projects.locations.datasets.hl7V2Stores.messages.delete.

curl command

To delete an HL7v2 message, make a DELETE request and provide the name of the parent dataset, the HL7v2 message ID, and an access token. The following sample shows a DELETE request using curl.

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID"

If the request is successful, the server returns a 200 OK HTTP status code and the empty body response in JSON format:

200 OK

{}

PowerShell

To delete an HL7v2 message, make a DELETE request and provide the name of the parent dataset, the HL7v2 message ID, and an access token. The following sample shows a DELETE request using Windows PowerShell.

$cred = gcloud auth print-access-token
$headers = @{ Authorization = "Bearer $cred" }

Invoke-WebRequest `
  -Method Delete `
  -Headers $headers `
  -Uri "https://healthcare.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID" | Select-Object -Expand Content

If the request is successful, the server returns a 200 OK HTTP status code and the empty response body in JSON format:

200 OK

{}
